Preparation of tert-amyl alcohol in a reactive distillation column. 2. experimental demonstration and simulation of column characteristics

摘要

Reactive distillation has been proposed as a means of enhancing the conversion for reactions whose progress is limited by chemical equilibrium. In the p[resent work, reactive distillation tests were carried out for the hydration of isoamylene (2-methyl-2-butene) to 2-methyl-2-butanol (tert-amyl alcohol or TAA) in a 5.3-cm column using a bale-type catalytic packing. Acetone was used as a solvent to avoid formation of a second liquid phase and also to enhance the rate of reaction.
